I lived in Northern Ireland until 1987 and was a mad stock car racing fan, starting off at Ballyskeagh outside Newtownards, then moving to a track in a Carrowdore quarry, followed by Portadown, Dunmore Stadium, Ballymena and Aghadowey. Great memories and I have loads of photos from most of those tracks. You can still see the Ballyskeagh track on Google Earth!
